The Seoul Star Cluster, which was controlled by Klent, was separated from the Colton Star Cluster by a barren cosmic belt. After the war between the Star Clusters broke out, the stargates to both Star Clusters were temporarily shut, and troops could only cross the border illegally through the barren cosmic belt.
A large fleet of troops passed through the barren cosmic belt and entered the borders of Colton, the West Wind Star System.
This was a vanguard force with the intention of probing the enemy. There were fifteen Expedition Level flagships, thousands of frigates and assault battleships, and a total of over ten thousand spaceships.
There were twenty-six Calamity Grade Supers, including Tyrant's Eight Vanguard Official.
The commander of the expedition fleet was Jorde, the individual in charge of Bloodshed Land's Military Strategy Department. He was a Grade A Super and one of Tyrant's old subordinates.
